Browsing: Galaxy Evolution
Galaxy evolution refers to the complex processes through which galaxies form, grow, interact, and change over cosmic time. From the earliest proto-galaxies in the young universe to the vast, structured systems we observe today, galaxies undergo dynamic transformations driven by star formation, mergers, black hole activity, and the influence of dark matter. Astronomers study galaxy evolution using observations across the electromagnetic spectrum and deep-sky surveys, often looking billions of years into the past. Understanding how galaxies evolve helps illuminate the broader history of the universe, including the conditions that led to the formation of stars, planets, and potentially life.
